उत्तर
When silicon dioxide (SiO2) is heated with hydrogen fluoride (HF), it forms silicon tetrafluoride (SiF4). Usually, the Si–O bond is a strong bond and it resists any attack by halogens and most acids, even at a high temperature. However, it is attacked by HF
\[\ce{SiO_2 + 4HF -> SiF_4 + 2H_2O}\]
The SiF4 formed in this reaction can further react with HF to form hydrofluorosilicic acid.
\[\ce{SiF_4 + 2HF -> H_2SiF_6}\]
